Trump became the first sitting US president to meet a North Korean leader when he sat down with Kim Jong-un in Singapore in June 2018. The summit was choreographed as a historic breakthrough, complete with gestures such as handshakes, flags and sweeping promises of denuclearisation.

President Vladimir V. Putin has long said he wants to sit down with President Trump. The reason: He believes that such a meeting, rather than just progress on the battlefield, is his best chance for securing a victory in his war against Ukraine.

The Kremlin says a meeting between Russian President Vladimir Putin and U.S. President Donald Trump has been agreed.
